Thomas Friel, 21, was shot in Creggan on 18 May 1973 after returning from a night out. He died four days later.
A new inquest into his death will begin later this year.
The BBC reports that counsel for the coroner has appealed for anyone who has not yet come forward to contact the Coroner’s Service.
At a hearing in Derry on Tuesday, a solicitor for the Friel family said he was unaware of any outstanding witnesses.
Coroner Joseph McCrisken told the hearing the inquest would begin in Derry courthouse on Monday, November 1 this year.
The new inquest was ordered by the Attorney General in 2014 after fresh documents revealed the Ministry of Defence knew rubber bullets were more dangerous than had been previously admitted.
